You can live without a functional liver, but then you have to go through dialysis. And you can live even if you have an entire lung removed. The spleen can be removed if it's damaged and you'd still live. However, people without a spleen are more prone to infections.
Also, women can have their uterus removed in a hysterectomy as a treatment for cancer, or other reasons.
But of course, you'd need your heart, brain, at least one lung and one kidney to survive.
Its either B or D. That's about all i can do. sorry
Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
D. The rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
Explanation:
It is important to consider that Kenny hikes all day but at a steady pace, whereas Janelle runs very fast. So Kenny's case, the supply of oxygen is sufficient to maintain aerobic respiration within the muscle cells. During this process only CO2, Water, and ATP are produced; therefore, there is no oxygen debt. We should keep in mind that the body shifts to anaerobic metabolism only when the supply of oxygen is limited.
In Janelle's case, running fast would need energy at higher rates and the supply of oxygen would not be sufficient to generate a high amount of ATPs. Therefore, to compensate for this deficiency, cells will start fermenting glucose to lactic acid and produce ATP and maintain energy demands. This lactic acid causes fatigue and this is why Janelle has aching and breathing hard. Breathing hard is also automatic reflux to inhale more oxygen and meet oxygen demands but even breathing hard would not be able to make it and the body will shift to anaerobic respiration automatically.
Answer:
digested into simple sugars :)
Answer:
With the concentration gradient through passive Transport
Explanation:
I haven't taken biology recently, but if I'm not mistaken, cells that use ATP can only passively do things.
